TRANSPORT AIRPLANE CRASH SIMULATION, VALIDATION AND APPLICATION TO CRASH DESIGN CRITERIA. IN: CONFERENCE PROCEEDINGS OF ENERGY ABSORPTION OF AIRCRAFT STRUCTURES AS AN ASPECT OF CRASHWORTHINESS (66TH), HELD IN LUXEMBOURG ON MAY 1-6 1988

This paper presents a brief desscription of the evolutionary development of program KRASH to its most recent release, KRASH85, and provides some background to delineate various program features as well as to illustrate the range of aircraft configurations and impact conditions for which the program has been validated. The results of the transport airplane correlation effort is used in a subsequent parametric study to formulate a crash design velocity envelope. Tthe flow diagram provided describes the sequence of this effort and the manner in which analytical and experimental data are integrated. Parametric analyses section test and full-scale crash test results are utilized and presented in the form of acceleration time histories at the cabin floor. The dynamic pulse parameters, namely velocity change, duration of excitat ion and peak acceleration amplitude, are related to potential seat dynamic test requirements. The transport crash design envelope, along with additional available data, is used to assess the effect of airplane size on floor acceleration pulses in a survivable crash environment.
